Abstract
Abstract A magazine fed clip tool of the stationary anvil type, and which utilizes closely nested clips or seal blanks for clinching ligatures or wires in the anvil. A clip is automatically fed to the clip tool and the clip tool preforms the clip into a nonnestable condition, after which the preformed clip is driven into the anvil jaw to be clinched about ligatures or wires. The method provides for stripping a clip from a closely nested stack, preforming the clip to a non-nestable condition and then clinching it about at least a pair of wires to form a clinched assembly.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
102 words
A method of forming a clinched assembly of a clip and at least a pair of wires, the steps comprising providing a stack of closely nested clips having a central web and a pair of leg sections divergingly projecting from said central web, stripping a clip from said nested stack and moving it to a first position, moving it from said first position to a second adjacent position while decreasing the divergence of said leg sections, then moving it from said second position to a third closely adjacent position while wrapping said leg sections about said wires to form a clinched assembly.
Claim 2
Independent Claim
102 words
A method of forming a clinched assembly of a clip and at least a pair of wires, the steps comprising providing a stack of closely nested clips having a central web and a pair of leg sections divergingly projecting from said central web, stripping a clip from said nested stack and moving it to a first position, moving it from said first position to a second adjacent position while decreasing the divergence of said leg sections, then moving it from said second position to a third closely adjacent position while wrapping said leg sections about said wires to form a clinched assembly.
Claim 3
Dependent Claim
21 words
In the method of claim 1 in which the steps of moving from said first to said third positions are continuous.
Claim 4
Dependent Claim
30 words
In the method of claim 1 in which said movement to said first position is in a direction normal to the direction of movement from said first and second positions.
Claim 5
Dependent Claim
32 words
In the method of claim 1 in which one clip is moved from said first to said second position and another clip is moved from said second to said third positions simultaneously.
Claim 6
Dependent Claim
106 words
In a power-operated clip tool for preforming closely nested clips each having a pair of diverging leg sections prior to clinching the clips about at least a pair of wires, means for stripping and feeding a nested clip into said clip tool, preforming means for reducing the divergence of said pair of leg sections by pushing the ends of said leg sections towards each other, a clinching anvil having a stationary jaw, driving means for driving a clip past said preformer toward and into said jaw, and means for moving said driving means between a first position remote from, and a second position in said jaw.
Claim 7
Dependent Claim
106 words
In a power-operated clip tool for preforming closely nested clips each having a pair of diverging leg sections prior to clinching the clips about at least a pair of wires, means for stripping and feeding a nested clip into said clip tool, preforming means for reducing the divergence of said pair of leg sections by pushing the ends of said leg sections towards each other, a clinching anvil having a stationary jaw, driving means for driving a clip past said preformer toward and into said jaw, and means for moving said driving means between a first position remote from, and a second position in said jaw.
Claim 8
Dependent Claim
24 words
In the clip tool of claim 5 in which said preformer is oscillatably mounted to gradually push said leg section ends towards each other.
Claim 9
Dependent Claim
38 words
In the clip tool of claim 6 in which said driving means comprises a driver assembly defining a cam slot in which a cam ball is positioned, said driver assembly being movable between said first and second positions.
Claim 10
Dependent Claim
24 words
In the clip tool of claim 7 in which said preforming means confronts said cam ball and said cam ball oscillates said preforming means.
Claim 11
Dependent Claim
57 words
In the clip tool of claim 8 in which said preforming means defines a ball notch to which said cam ball is transferred by said driver assembly when said driver assembly is moved from said first position toward said second position and from which said cam ball is transferred as driver assembly returns to said first position.
Claim 12
Dependent Claim
27 words
In the clip tool of claim 5 in which said driving means comprises a driver assembly having a clinching blade for clinching a clip in said anvil.
Claim 13
Dependent Claim
56 words
In the clip tool of claim 10 in which said driver assembly further comprises a driver blade for moving a clip from said first position past said preforming means to an intermediate position remote from said second positiOn, said clinching blade being adapted to move a preformed clip from said intermediate position to said second position.
Claim 14
Dependent Claim
62 words
In the clip tool of claim 10 in which said preforming means is oscillatably mounted and said driver assembly defines a cam slot seating a cam ball, and said preforming means defines a ball transfer notch, whereby said cam ball is transferred from cam slot to said transfer notch as said driver assembly is moved from first position to said second position.
Claim 15
Dependent Claim
95 words
A clip tool comprising in combination a housing and frame assembly, a stationary clinching anvil having a jaw secured to said housing, a clip magazine, a power-actuated clinching blade for driving a clip into said anvil to clinch said clip around a pair of members to be clinched, means for ejecting clips from a nested stack of clips from said magazine into said housing and frame assembly, and means in said housing and frame assembly for preforming a clip into a substantially non-nestable condition at a position remote from the jaw of said clinching anvil.
Claim 16
Dependent Claim
95 words
A clip tool comprising in combination a housing and frame assembly, a stationary clinching anvil having a jaw secured to said housing, a clip magazine, a power-actuated clinching blade for driving a clip into said anvil to clinch said clip around a pair of members to be clinched, means for ejecting clips from a nested stack of clips from said magazine into said housing and frame assembly, and means in said housing and frame assembly for preforming a clip into a substantially non-nestable condition at a position remote from the jaw of said clinching anvil.
